About TIMSS 2015
In 2015, IEA and its TIMSS & PIRLS International Study Center at Boston College conducted TIMSS 2015 at fourth and eighth grades and TIMSS Advanced 2015 for students in the ﬁnal year of secondary school enrolled in special advanced mathematics and physics programs or tracks. Both TIMSS 2015 and TIMSS Advanced 2015 provide 20-year trend measures for countries that participated in the ﬁrst TIMSS assessments in 1995.
TIMSS 2015 and TIMSS Advanced 2015 continue the long history of international assessments in mathematics and science conducted by IEA – the International Association for the Evaluation of Educational Achievement. IEA is an independent international cooperative of national research institutions and government agencies that has been conducting studies of cross-national achievement since 1959.
The TIMSS 2015 Assessment Frameworks provides the foundation for the ﬁve international assessments to take place as part of IEA’s TIMSS 2015.
The TIMSS 2015 Encyclopedia: Education Policy and Curriculum in Mathematics and Science is a comprehensive compendium of how mathematics and science are taught around the world.
The TIMSS 2015 mathematics achievement results are reported as average scores and distributions on the fourth and eighth grade TIMSS 2015 mathematics achievement scales.
The TIMSS 2015 science achievement results are reported as average scores and distributions on the fourth and eighth grade TIMSS 2015 science achievement scales.
